HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: Water that is lukewarm. Tepid bathwater refers to water that is neither too hot nor too cold, but rather at a moderate or lukewarm temperature. This is the ideal temperature for bathing as it is comfortable and soothing. Choice A is incorrect because tepid water is not salty. Choice C is incorrect because tepid water is not icy; it is warmer than cold water. Choice D is incorrect because tepid water refers to the temperature of the water, not the quantity.

Correct Answer: C

Rationale: The correct answer is C: nostrum. A remedy is a substance or treatment that cures ailments. "Nostrum" is a synonym for remedy or cure, making it the most appropriate choice. A: inoculation refers to the process of introducing a vaccine to prevent disease. B: indicator is something that provides information or points out a condition, not necessarily a cure. D: serum is a component of blood and not specifically related to curing ailments. Therefore, C is the correct answer because it directly relates to the concept of a remedy curing ailments.

Correct Answer: D

Rationale: The correct answer is D: Commotion. In the given sentence, 'tumult' is used to describe a state of confusion and disorder in the emergency room. A commotion refers to a noisy disturbance or uproar, which perfectly fits the context of the sentence. Siren (A) refers to a loud noise, not the overall chaotic situation. Distress (B) and suffering (C) are related to feelings of pain or discomfort, but they do not capture the sense of chaos and noise implied by 'tumult' in this context.

Correct Answer: D

Rationale: The correct answer is D: Bond. Rapport refers to a close and harmonious relationship or connection between individuals. In the context of the sentence, 'developed a quick rapport' implies that the nurses and teenage aides quickly formed a close bond or connection. This is evident through their ability to communicate effectively, trust each other, and work well together. Choice A: Performance is incorrect because rapport does not refer to performance but rather the relationship between individuals. Choice B: Narrative is incorrect because rapport does not relate to storytelling but rather the bond or connection between people. Choice C: Manner is incorrect because rapport is not about the way something is done but rather the quality of the relationship. In summary, the word 'rapport' in this sentence specifically means a bond or connection between the nurses and teenage aides, making choice D the correct answer.
